lower end upon a base plate and is capable' of swinging in opposite directions.

A. further object of the invention is to provide a semaphore arm pivotally mounted at its lower end upon a supporting base plate with lock devices arranged in the path of swinging movement of the arm in either direction to control the movement thereof, the invention also providing for an extensible semaphore arm with a lamp bracket securedto the head thereof.

lVith the above and other objects in view, the invention consists in the novel form, combination and arrangement of parts hereinafter more fully described and shown in the accompanying drawings, wherein like reference characters indicate similar' parts throughout the several views.

In the drawings,-

Fig. 6 is a detail sectional view taken on line lvl-VI of Fig. 3 showing the semaphore post in lowered horizontal position,

i and illustrated one embodiment of the invention, the reference numeral 1 designates the mounting base for a pivoted semaphore post 2 carrying a semaphore arm 3 at the upper end thereof and upon which a hook l is mounted for supporting the signal lamp 5 shown by dotted lines in Fig. 1.

The semaphore post structure will first be described, the same being extensible and embodying a lower section 6 longitudinally slotted as at 7 to provide a guideway for the upper extension 8, vertically guided therein by the straps 9 and retained in its adjusted position by the key 10 passing through registering openings formed in the base section 6 and the upper extension 8 as shown in Figs. 1 and 2. Any preferred type of semaphore arm 3 may be secured to the upper end of the post2, the arm 3'being detachable.

for this purpose.

As shown more clearlyin Fig. 4, the mounting base 1 is provided with a raised central portion 11 having the lower face thereof cut away to provide a recess 12 that is closed by the bottom strip 13 lying flush with the lower face of the mounting base plate 1 and secured in position by the screws 14. To provide for the side swinging of the semaphore post 2, the lower end of the lower section 6 thereof is rounded as at 15 and carries bearings 16, the lower side of the end 15 engaging the upper face of the closure strip 13 whilethe bearings 16 engage the upper walls' 17 of the recess 12. The upper face of the raised central portion 11 as shown in Fig. 3 is transversely slotted as at 18 to permit the lateral pivoted swinging of the'semaphore arm 2 as will at once be obvious.

Means is associated with each side of the mounting base plate 1 and engages the semaphore post 2 to hold the same either vertically or horizontally positioned at either side of the base plate, such means including a locking lever as shown in Fig. 7 by the reference numeral 19 having one end 2O thereof providedvwith a. central opening 21 forV mounting on the pivot pin 22 carried by the base plate 1, the end 20 of the lever being received in therecess 23 in the raised central portion 11 while the opposite end 24 of the lever extends into the recess 25 arranged in the base plate 1 at the opposite side of the transverse passage 18. The intermediate portion of the lever 19 is provided with a cross head 26 that is positioned in the trans verse opening 18, that portion of the lever 19 beneath the cross head 26 being out away to provide an inverted V-shaped notch as illustrated in F ig. I aiiording a clearance for the semaphore arm 2 when the same is in theV horizontal position shown in F ig. 6. In order to retain the lever 19 in locked position, the end 24 thereof is provided with an end cut providing a hook 27 having a lower beveled face 28 that slides over the upper beveled face 29 of the sliding latch 30 shown more clearly in Figs. 3 and 5, the latch 30 being slidably mounted in the horizontal recess 31 that is alined with the recess 25 and containing a coil spring 32 engaging the inner end of the latch 30, thusnormally forcing the latch in a direction for engagement with the lever 19. To manually retract the latch 30 from engagement with the locking lever 19, an operating knob 33 is fixed to the latch 30 and slidably extends throughV the side slot34 in the side wall of the base plate 1 and in communication with the recess 31. When the latch 30 is moved to a disengaging position relative to the lever 19, the ring 35 secured in the opening` 36 in the end 24e of the lever may be employed for shifting the lever upon its pivot pin 22 in the operation thereof.

As shown in Figs. 1 and 3, the base plate 1 is provided with spike receiving openings 3'? for mounting the base plate upon a tie 38 or other support. W'hen the semaphore post 2 is in the vertical position shown in Figs. 1 and 2 and it being desired to lower the same to the horizontal position shown by full lines in Fig. 6, the desired lever 19 is released from engagement with the latch 30 by shifting the latch against the tension of the spring 32 to free the same from the lever hook 27, after which the lever 19 is moved upon its Vpivot pin 22to displace the cross head 2G yfrom the transverse slot 18 and permit the side swinging movement of the post 2. When the post is moved to its horizontal position, the same is of an area substantially to fill the lower end of the passage 18whereupon the lever 19 is again lowered to its locked position with the head 2() overlying the arm 2 and with the hook 27 automatically engaging the latch 30 by the cooperating bevel faces 28 and 29. The semaphore arm 2 may be locked in a hori zontal position on either side of the base plate 1 and the same may also be locked in a vertical position between the spaced ends ci? the two cross heads 26 as shown in Fig. 3. The vertical or longitudinal adjustment ci' the post 2 is accomplished by the section 8 sliding in the section 6 and locked in its adjusted position by the key 10. ,The arm 3 may be employed for signaling during daylight, while during darkness a lamp or other luminant may be supported upon the hook 4 carried by the arm 3.

lvVhile there is herein shown and described the preferred embodiment of the invention, it is nevertheless to be understood that minor changes may be made in the same without departing from the spirit and scope of the invention as hereinafter claimed.

What is claimed asnew is:

1. A semaphore oit' the type described comprising -a mounting base, a semaphore post pivoted thereon, a lever pivoted at each side oi the plate and engaging the post to hold the same either vertically or horizontally positioned, said base plate being transversely slotted at Ythe pivot point of the post, cross heads carried bythe levers extending into said slot and engaging the sides of the post when the same is vertically positioned and overlying the post when horizontally positioned.

2. A semaphore of the type described comprising a mounting base, a semaphore post pivoted thereon, a lever pivoted at each side of the plate and engaging the post to hold the same either vertically or horizontally positioned, said base plate being transversely slotted at the pivot point orn the post, cross heads carried by the levers extending into said slot and engaging the sides of the post when the same is vertically positioned and overlying the post when horizontally positioned and locking means Jfor the swinging ends of the levers.

3. A semaphore of the type described comprising a mounting. base, a semaphore post pivoted thereon, a lever pivoted at each side of the plate and engaging the post to hold the same either vertically or horizontally positioned, said base plate being transversely slotted at the pivot point oi the post, cross heads carried by the,V levers extending into said slot and engaging the sides of the post when the same is ventically` positioned and overlying the post when horizontally positioned and tensione*L latches engaging the swinging ends oit the levers to hold the same in locked position.

4. A. semaphore oi' the type described comprising a mounting base plate, a semaphore post pivoted thereon and independentlf.r operating means arranged in the path et movement of the semaphore post coperating therewith to hold the postV either vertically or horizontally positioned.
